First of all i want to say thanks to mercedes shop for having such a great forum if it wasnt for u guys i would probably go bankrupt .Here is my problem i would drive the car for about 1 hour let it seat for about 15 mins then i would smell gas then i would try to start it , it would die the first try then go again with a very rough idle i would floor it after about 5 to 10sec i would go and everything would be find
just replace ovp , cat converter, new plugs ,wires. thanks guys
